No, the tax authorities only charge the cost of the tax registration certificate. Tax depends on what kind of taxpayer you are. If you are an individual industrial and commercial household, your monthly sales income is less than 20 thousand, and you don't have to pay a penny. If it is an enterprise, the approved collection mainly refers to the enterprise income tax, and the tax amount is calculated according to the approved collection rate. Another is that when you buy an invoice, you have to charge the invoice cost, which is very small.
